Sasquatches, or Bigfoots, are large ape-like, or humanoid creatures that purportedly live in North America, mostly along the Pacific Coast states and provinces. These hairy creatures are generally larger than humans, 6' - 10' tall, and can weigh more than 500 pounds. They typically have brown or reddish brown hair (not fur).
The word "Sasquatch" comes from a Pacific Northwest Native American word for "wild man" or "hairy giant", and is a part of many Native American legends. The first recorded "sighting" of a Sasquatch by a white man was in 1811. (See Bigfoot of North America)
The term "Bigfoot" was coined in the 1950's from large humanoid footprints that were found in California. Other names for this North American hominid include "skunk ape", "skookum", and "mountain devil". More ape-like cryptids (animals whose existence has been unproven) have been reported from around the world, like the yeti (abominable snowman) from Himalayan Nepal and Tibet.
Rhettman Mullis, from Bigfootology, thinks that fairytales about ogres, trolls, giants, and bogeymen may really be from sightings of Bigfoot-like animals in different parts of the world. That's a fascinating idea, don't you think?
